Biometric design of complete dentures related to residual ridge resorption

The aim of this study was to determine whether the location of the incisive papilla, the extent of the alveolar bone remaining on the facial side of the palatal-gingival margin in the canine region, and the height of the palatal vault in the molar region are associated with factors that may affect the volume of the residual ridges in an edentulous maxillae. Results suggest that duration of the edentulousness and skeletal mineral status are important factors in the resorption of the residual ridges in the maxillae. The location of the incisive papilla and the thickness of the ridge on the facial side of the palatal-gingival margin are associated with these two factors.
